necessary libraries and/or headers.  Check the mkmf.log file for more

    Install the library or try one of the following options to extconf.rb:

      --with-xml2-config=/path/to/xml2-config
      --with-xml2-dir=/path/to/libxml2
      --with-xml2-lib=/path/to/libxml2/lib
      --with-xml2-include=/path/to/libxml2/include



Gem files will remain installed in /home/ubuntu/.rvm/gems/ruby-1.8.7-p374@ieasy/gems/libxml-ruby-2.7.0 for inspection.
Results logged to /home/ubuntu/.rvm/gems/ruby-1.8.7-p374@ieasy/gems/libxml-ruby-2.7.0/ext/libxml/gem_make.out

An error occurred while installing libxml-ruby (2.7.0), and Bundler cannot continue.
Make sure that `gem install libxml-ruby -v '2.7.0'` succeeds before bundling.

不太确定这里出了什么问题。这适用于我的另一个具有相同 ruby​​ 和 rails 版本的盒子。

一直在尝试解决这个问题，但没有成功。

请帮忙。 :( .. 谢谢!

首先，安装libxml2-dev

sudo apt-get install libxml2-dev
